Autocar Industries is recalling 5,286 trucks to address their potential for excessive engine crankcase pressures that might ultimately pose a fire risk, according to the National Highway Traffic Safety Administration.
Autocar is issuing two separate recalls, the largest of which affects 5,245 Xpeditor trucks in the 2008 to 2016 model years. The Xpeditor trucks, which have Cummins natural gas-operated engines, were manufactured from July 30, 2007, through April 29 of this year.
Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather. This condition might allow engine oil to come into contact with hot surfaces and pose a fire risk, NHTSA said.
Cummins will notify truck owners on behalf of Autocar, and Cummins service centers will administer the repairs. These repairs will include securing the ends of the 90-degree elbow and reprogramming the electronic control module (ECM) with software that can adjust the engine output under misfire conditions to limit crankcase pressures.
Cummins will perform the necessary repairs, free of charge. Autocar’s number for this recall is ACX-1503.
The second recall involves 41 Xpert and XSpotter trucks in the 2014 through 2016 model years. They have Cummins Westport ISL G natural gas engines. The problem and recall remedy are similar to the first recall. Autocar’s number for the second recall is MDTT-01.
Both safety recalls are expected to begin this month.
Truck owners can reach Autocar customer service at (765) 489-5499 or Cummins at (800) 343-7357.
